• ffmpeg silenceremove - hear what bits are removed

  7 avril 2020, par jimo

  ffmpeg silenceremove is pretty cool. im loving it. i can trim 3 second silences to 2 seconds and reduce a 1.5 hour file of spoken audio down 3 or 4 minutes (depending on the speaker).

  



  once in a while I do hear my choice for stop_threshold (ie-40dB on audio only analog file) does cause the end of a word to be clipped, just here and there when the speaker trails off softly at the end of the word.

  



  is there any way to output what is trimmed to a file ? so I can listen to it and get an idea of just how often this word clipping happens ?

  



  thanks !

  


• ffplay won't with with more than 6 audio channels

  13 juin 2020, par Hiko Haieto

  I am trying to stream (raw) video and audio from a capture device as part of my home media setup (with my pc acting similarly to a receiver in a typical home theatre setup), but the biggest problem I haven't been able to get past is that I haven't been able to get ffplay to work with all 8 channels in 7.1 streams - two simply get dropped, despite it recognising 8 channel input or me specifying a 7.1 layout.

  



  I have been able to confirm that all 8 channels are present in the source by first using ffmpeg to save the output of a speaker test to a file and playing that back with both mplayer (which works) and ffplay (which doesn't). I might simply use mplayer if it weren't for the fact that piping output from ffmpeg adds too much latency for real-time use. I am using libSDL version 2.0.12 and ffplay 4.2.3, both of which are the latest at the time of writing and are ostensibly supposed to support 7.1 audio.

  



  Using output recorded from speaker-test -c 8, I am using the following to play it back in mplayer :

  



  mplayer -channels 8 -rawaudio channels=8 -format s16le -demuxer rawaudio speaker-test.pcm


  



  and the following to play it back in ffplay :

  



  ffplay -f s16le -ac 8 -af 'channelmap=channel_layout=7.1' speaker-test.pcm


  



  No matter what I try, ffplay is dropping the two side channels. Why might ffplay not be producing output for all 8 channels, and how might I fix it ?
